THE BOLOGNA MIXTAPE IS FINALLY OUT :)
This is our best project. Thank you for listening ❤️
Recorded: Pacific Beat
Mixed & Recorded by: Alan Sanderson
Mastered: David Bates
Album Art: @cat_vomit
Listen anywhere :)
Thurs 4/30, indie/alt rock w Pleasure Pill (acoustic), The Babygirls & Squeaky Buddha! First time Pleasure Pill & Babygirls have played our stage, but definitely not the last 💗 And stoked to bring Squeaky Buddha back since they relocated to Australia. Some serious talent for not much moolah.
Doors 7pm, 21+, $5

A modern wind turbine converts the kinetic energy (motion energy) of moving air into electrical energy you can use in homes and cities.
At its core, it’s an elegant chain of energy transformations:
Wind → Rotational Motion → Mechanical Energy → Electrical Energy 1. Catching the Wind – The Blades
Each turbine has 3 long blades, often 40–80 meters each, shaped like airplane wings (aerofoils). • Airflow dynamics:
As wind flows over each blade, the curved shape creates a pressure difference — lower pressure on the top side and higher on the bottom.
This difference produces lift, just like on a plane’s wing, which makes the blades spin. • Optimal angle:
The pitch (angle) of the blades can adjust automatically via motors inside the hub to catch the perfect amount of wind — too little and it’s inefficient; too much and it risks damage. • Efficiency range:
Turbines typically start spinning at around 3–4 m/s (gentle breeze), reach optimal generation around 12–15 m/s (strong wind), and shut down for safety at 25 m/s+ (gale force).All three blades are bolted to a central hub, forming the rotor.
This rotor connects to a low-speed shaft inside the nacelle (the big box on top of the tower). • The rotor typically spins at 10–20 RPM — pretty slow. • But electricity generation needs hundreds or thousands of RPM, so we need something to speed it up…The gearbox multiplies that slow rotation speed into something usable for the generator. • It connects the low-speed shaft from the rotor to a high-speed shaft going into the generator. • The gearing ratio can be around 1:100, meaning if the rotor turns once, the generator shaft turns 100 times. • Gearboxes are massive — often weighing several tons — and filled with special oil for cooling and lubrication.
⚙️ Some newer turbines skip the gearbox entirely (called direct-drive turbines) by using large, slow-rotating generators with permanent magnets instead.
